Precision is key in machining and structural applications. The V slot designs come in various sizes, which allow for precise joints and secure fits. They also allow adjustments in case of any measurement errors.

T Slot vs. V Slot Extrusion Weight Options

● Heavy Duty - This aluminum extrusion weight offers optimum sturdiness. It is tailored for loaded structures and those involving linear motion. It is also used to manufacture heavy machinery. The main advantage of this weight option is the enhanced structural support and efficiency in heavy weight bearing applications. Heavy duty T slot and V slot extrusions are more expensive due to their bulky material.

● Standard - These are T slot and V slot extrusions with a sprinkle of all the strength properties (light and heavy), which make up a blend of average weight profiles. It is the most popular weight option for medium-level intricate applications. Additionally, they cost less than the heavy-duty applications. You can use them for standard workbenches and shelving units.

● Lightweight - This is the cheapest weight option due to its significantly reduced weight. Despite its lightweight properties, it offers durability and efficiency for less demanding applications. Some common products with lightweight T slots and V slots are lightweight framings and machinery.

Key Differences Between T Slot and V Slot Aluminum Extrusions

Edges

One way you can tell apart a T slot from a V slot is by the difference in the edges. The V slot edges are smoother and are beveled, while the T slot ones resemble a T shape.

Another difference in the physical characteristic is that V slots have rails that make linear motions easy in motion control applications.

Finishing Options

T slots are mostly sold untreated. V slots, on the other hand, are available untreated, or you can have them anodized in black.

Aluminum looks good and shiny whether you choose to finish it or not. Finishing options like paint are unsuitable for both V slots and T slots as it easily chips and covers up the authentic look of the aluminum metal.

Connecting Hardware

T slots and V slots are connecting extrusions. However, they need other hardware accessories to serve this function.

Most of this connected hardware is suitable for both extrusions, but they come at varying costs. You can use T nuts or fasteners or go for cheaper options like custom-making 3D connectors.

Cost

V slots offer higher efficiency than T slots. They allow for wheel sliding in framing. For this reason, you will get them at a higher cost than their T slot counterparts. Another contributing factor to the higher cost is that V slots are modern, while T slots are considered traditional.

Applications

There are different types of V slot and T slot extrusions, each with unique applications. Other parameters that affect their uses are weight and dimension. Applications range from DIYs to more complex uses like framings, 3D printers, construction assembly lines, housings, etc. Although both are interchangeable, you can achieve higher efficiency by choosing the one that best suits your application.
